About the CCL

We design software that enables our collaborators to easily harness large scale distributed systems such as clusters, clouds, and grids. We perform fundamental computer science research in that enables new discoveries through computing in fields such as physics, chemistry, bioinformatics, biometrics, and data mining.

The Chirp filesystem has been in production use by the ATLAS experiment at the Large Hadron Collider facility in Geneva. The Chirp file server provides staging access to analysis data accessed by pilot jobs dispatched through the Panda workload management system. The system has been running for about 2 years on a 2 TB filesystem with a constant workload of about 10K file stores per day. The key capability provided by Chirp is the ability to provide fine-grained authorization to data based on the
Globus Security infrastructure.
